有没有办法可以使用ES7 Set或Map方法比较两个对象？

function deepEqual(obj1, obj2, map = new Map()) {
    if (obj1 === obj2) return true;

    if (typeof obj1 !== 'object' || obj1 === null ||
        typeof obj2 !== 'object' || obj2 === null) {
        return obj1 === obj2;
    }

    if (map.has(obj1)) return map.get(obj1) === obj2;

    map.set(obj1, obj2);

    const keys1 = Object.keys(obj1);
    const keys2 = Object.keys(obj2);

    if (keys1.length !== keys2.length) return false;

    for (const key of keys1) {
        if (!keys2.includes(key) || !deepEqual(obj1[key], obj2[key], map)) {
            return false;
        }
    }

    return true;
}

// 示例
const objA = { a: 1, b: { c: 3 } };
const objB = { a: 1, b: { c: 3 } };
console.log(deepEqual(objA, objB)); // 输出: true

function sortedDeepEqual(obj1, obj2) {
    const sortedKeys1 = Object.keys(obj1).sort();
    const sortedKeys2 = Object.keys(obj2).sort();

    if (sortedKeys1.length !== sortedKeys2.length) return false;

    for (let i = 0; i < sortedKeys1.length; i++) {
        const key = sortedKeys1[i];
        if (!sortedDeepEqual(obj1[key], obj2[key])) {
            return false;
        }
    }

    return true;
}
